The eastern white-cedar is also called northern white-cedar, 
arborvitae and swamp-cedar. The name arborvitae or "tree of life" dates from the 
16th century when the French explorer Jacques Cartier learned from the Indians 
how to use the tree's foliage to treat scurvy. 
Description 
General - small-sized, averaging 12 m (40 ft) 
high, evergreen. Crown is conical, dense, layered and compact. Branches arching. 
Trunk strongly tapered, often gnarled with thin reddy-brown bark. Branchlets 
yellowish-green, clad in sheathing foliage, forming flat, fan-shaped sprays.
 Leaves - 
opposite; scale-like, closely overlapping, successive pairs at right angles; 
upper and lower leaves flat, with a protruding resin gland, lateral leaves 
folded, clasping the flat leaves. 
Flowers - monoecious, the male and female 
flowers of eastern white-cedar are usually borne on separate twigs or 
branchlets; they are tiny, terminal, cone-like bodies. Male flowers are 
yellowish and arise from branchlets near the base of the shoot; female flowers 
are pinkish and appear at the tips of short terminal branchlets. 
Fruit - Ripe cones are pale cinnamon brown, 
oblong, and 8 - 13 mm (0.3 - 0.5 in) long. Woody scales of mature female cones 
enclose double-winged seeds which are released the year after development.
Habitat 
Common throughout Northwestern Ontario, northern part of Asia,  
and Europe, the eastern white 
cedar is most often associated with cool, moist, nutrient-rich sites, 
particularly on organic soils near streams or other drainage-ways, or on 
calcareous mineral soils. 
The eastern white-cedar type commonly grows in association with balsam fir 
and tamarack in the boreal region. 
Except when dense, eastern white-cedar stands usually have an undergrowth of 
shrubs and herbs. Speckled alder is commonly the most important shrub on the 
better sites. Other characteristic shrubs on the better sites (especially in 
swamps) include mountain maple, red-osier dogwood and Canada fly honeysuckle. On 
poorer sites they include Labrador tea, blueberries and wintergreen. 
Characteristic herbs on the better sites (especially in swamps) include dwarf 
raspberry, wild lily-of-the-valley and bunchberry. On poorer sites they include 
false Solomon's-seal. Ground cover is usually a mosaic of sphagnum and other 
mosses, liverworts and decaying logs. 
Uses 
The rot- and insect-resistant wood is used principally for 
products in contact with water and soil such as rustic fencing, posts, outdoor 
furniture, structures and saunas. Other important products include cabin logs, 
lumber, poles, and shingles. Smaller amounts are used for paneling, piling, 
lagging, pails, potato barrels, tubs, ties and boats (especially canoes). 
Recently, white-cedar has been used for making kraft pulp and it appears 
excellent for particleboard. 
Cedar leaf oil is distilled from boughs and used in medicines and perfumes; 
boughs are also used in floral arrangements and is a widely planted ornamental.
The northern white-cedar type is valuable for wildlife habitat, particularly 
for deeryards during severe winters. The tree is highly preferred by 
white-tailed deer for both shelter and browse. White-cedar is also utilized by 
such mammals as the snowshoe hare, porcupine, and red squirrel.
